Kinetic provides this skewer with every new trainer. Extra skewers may be purchased here.
NOTE: We strongly recommend replacing your bicycle's stock skewer with this skewer we've provide with the trainer (the Kinetic skewer is also safe for riding outdoors). We also recommend that you use the stock cone cups already installed on your kinetic trainer. You'll save wear and tear on your own skewer and be assured of a solid attachment for your bike.
